The Mangaia Swiftlet was
described in the year 2002 on the basis of subfossil bones, that were
found on the island of Mangaia.

The species was closely allied with the still living 'Atiu Swiftlet (Aerodramus
sawtelli (Holyoak)) from the islnd of 'Atiu, the neighbouring island
of Mangaia, but was
probably slightly larger than this species.
